Comprehensive Management Of Commensal Bats, Stephen C. Frantz, Brian R. Laniewicz
Comprehensive Management Of Commensal Bats, Stephen C. Frantz, Brian R. Laniewicz
Wildlife Damage Management Conference
This paper reviews the basic concepts behind a comprehensive management approach to managing commensal species, and then considers how this approach is applied to bats that live within and about the built environment. Management activities should take into consideration the whole environment in which the target species is active, including the periodic changes that occur within that environment. Comprehensive management includes a clear understanding of: the biology, behavior and ecology of the species to be managed; the environment in which that species is active (especially harborage location); and the appropriate intervention methods used to manage such species. Interventions fall under …
Evaluation Of Moderate And Low-Powered Lasers For Dispersing Double-Crested Cormorants From Their Night Roosts, James F. Glahn, Greg Ellis, Paul Fioranelli, Brian S. Dorr
Evaluation Of Moderate And Low-Powered Lasers For Dispersing Double-Crested Cormorants From Their Night Roosts, James F. Glahn, Greg Ellis, Paul Fioranelli, Brian S. Dorr
Wildlife Damage Management Conference
The double-crested cormorant (Phalacrocorax auritus) is the primary avian predator on the southern catfish industry, estimated to cause $5 million in damage per year. To date, the most effective strategy for alleviating cormorant depredations in areas of intensive catfish production is coordinated dispersal of cormorant night roosts with pyrotechnics. Many of these night roosts are located in waterfowl refuges or wetland habitat leased for waterfowl hunting. Thus, there is an increasing concern about the effects of cormorant harassment efforts on waterfowl and other wildlife inhabiting these sites in cypress-swamp habitat. To address the need for a roost harassment device that …
Special Resident Canada Goose Hunting Seasons In Pennsylvania - Management Implications For Controlling Resident Canada Geese, John P. Dunn, Kevin J. Jacobs
Special Resident Canada Goose Hunting Seasons In Pennsylvania - Management Implications For Controlling Resident Canada Geese, John P. Dunn, Kevin J. Jacobs
Wildlife Damage Management Conference
Special hunting seasons were first implemented in 1992 to help reduce the growth rate of Pennsylvania's rapidly expanding resident Canada goose (Branta canadensis) population. Special seasons timed to occur before and after fall migration were successful in harvesting resident and not migrant Canada geese. Since 1992, September and late season hunting opportunities have been gradually expanded to include the entire state. The special season harvest of resident Canada geese has increased from about 13,000 birds in 1992 to over 68,000 in 1999. Special hunting seasons now account for over 80% of the entire Canada goose kill in Pennsylvania. Despite the …

Behavioral Observations And Physiological Implications For White-Tailed Deer Treated With Two Different Immunocontraceptives, Gary J. Killian, Lowell A. Miller
Behavioral Observations And Physiological Implications For White-Tailed Deer Treated With Two Different Immunocontraceptives, Gary J. Killian, Lowell A. Miller
Wildlife Damage Management Conference
The results of a 6-year behavioral study of white-tailed deer (Odocoileus Viginianus) treated with two immunocontraceptive vaccines, porcine zona pellucida (PZP) and gonadotropin releasing hormone (GnRH) are summarized. Does were immunized late summer and early fall. In November, does were exposed to bucks and observations were made 2-3 times daily for one half hour through the end of February. Does were considered to be in estrus when they were the object of intensive sexual interest by the buck. Compared to controls, PZP-treated does had a significantly lower fawning rate and an increase in the average number of estrous cycles observed …
The Use Of Border Collies In Avian And Wildlife Control Programs, Nicholas B. Carter
The Use Of Border Collies In Avian And Wildlife Control Programs, Nicholas B. Carter
Wildlife Damage Management Conference
Airports attract large numbers of wildlife primarily because they offer immense tracts of foraging and nesting habitats free from the threat of predation. Border collies can serve as an effective means of wildlife control in these environments by introducing a predator into the ecosystem. Many wildlife dispersal methods seek to imitate predators or the effect of predators and become increasingly ineffective as wildlife habituate to the stimuli. However, border collies are true predators, representing an actual, not perceived, threat to wildlife thereby eliminating the problems of habituation. Six airports and military bases have initiated use of border collies at their …
Turkey Damage Survey: A Wildlife Success Story Becoming Another Wildlife Damage Problem, James E. Miller, Brain C. Tefft, Robert E. Eriksen, Mike Gregonis
Turkey Damage Survey: A Wildlife Success Story Becoming Another Wildlife Damage Problem, James E. Miller, Brain C. Tefft, Robert E. Eriksen, Mike Gregonis
Wildlife Damage Management Conference Proceedings
Wild turkey (Meleagris gallopavo) populations have been restored and enhanced through introductions and reintroductions in 49 of the 50 states to huntable populations within the last 30 years. Populations are presently estimated to exceed 4 million birds within the United States. In many states, wild turkey habitat includes woodlots interspersed with agricultural lands, and some of the highest known population densities of wild turkeys are found in such areas. This paper will report on existing research, examining perceived versus actual damage caused by wild turkeys. It will also provide information based on a recent survey of biologists from the State …

What Will The Disease Issues Of The Future Be?, Robert G. Mclean
What Will The Disease Issues Of The Future Be?, Robert G. Mclean
Wildlife Damage Management Conference Proceedings
The major categories of diseases of the future involving wildlife are zoonotic diseases of public health importance, domestic animal diseases of economic importance, and wildlife diseases and health of wildlife importance. The existing patterns of these diseases include exotic, introduced diseases (West Nile virus - WNV), emerging diseases (Lyme disease), re-emerging diseases (animal rabies), and continuing diseases (leptospirosis). Some significant emerging public health diseases are WNV, hantavirus, Lyme disease, hemorrhagic E. coli 0157:H7, and antibiotic resistant bacteria. Emerging domestic animal diseases also include WNV, E. coli 0157:H7, salmonella enterica, and spongiform encephalopathies. Whereas, emerging wildlife diseases are WNV, particularly in …

Coding Spreadsheets For Intervention Decisions In Wildlife Damage Management, Ray T. Sterner, H. Nicole Lorimer
Coding Spreadsheets For Intervention Decisions In Wildlife Damage Management, Ray T. Sterner, H. Nicole Lorimer
Wildlife Damage Management Conference Proceedings
Sterner (In press) described the use of a priori, theoretical analyses of crop/resource savings and benefit:cost ratios as a way of making intervention decisions in wildlife damage management. Iterative (1-variable-changed-at-a-time) calculations of these economic indices were computed for the use of zinc phosphide baits to control vole {Microtus spp.) populations in alfalfa (Medicago sativa). Results showed that indices displayed transitive effects — greater net savings and benefit:cost ratios were related to larger field-size, crop-damage and bait-effectiveness variables, but smaller bait-application fees. Ratios varied between 0.40 and 6.45, with -5-10% vole-caused damage required to produce returns on investments equal to the …
A Private Lands Approach To Controlling New Jersey's Deer Population, David Drake
A Private Lands Approach To Controlling New Jersey's Deer Population, David Drake
Wildlife Damage Management Conference Proceedings
In New Jersey, annual losses from white-tailed deer (Odocoileus virginianus) depredation to agricultural crops have been estimated as high as $10 million. Additional problems caused by the state's overabundance of deer include increasing vehicle/deer collisions, possible human health concerns regarding increasing incidences of Lyme disease, and a loss of flora and fauna diversity. In an effort to reduce deer numbers and minimize damage, both non-lethal and lethal management practices have been used with limited success. Hunter access to private lands remains the biggest impediment to effective deer management in New Jersey. I propose an incentive-based program to increase lease and …
Efforts To Enhance Stakeholder Communications In North Carolina's Wildlife Damage Control Agent System, Peter T. Bromley, Carl W. Betsill
Efforts To Enhance Stakeholder Communications In North Carolina's Wildlife Damage Control Agent System, Peter T. Bromley, Carl W. Betsill
Wildlife Damage Management Conference Proceedings
In 1995, North Carolina Wildlife Resources Commission (NCWRC) established policy and rules for handling of nuisance wildlife by Wildlife Damage Control Agents (WDCA). The policy required a one-day long training session, culminating in an open book, certification examination. The North Carolina Cooperative Extension Service (NCCES) conducted the training and administered the examination. The certification-training program covered principles of wildlife damage management, wildlife laws and regulations, humane handling of animals and euthanasia, human health risks from exposure to wildlife, professional ethics, and sources of technical information. Between Octoberl995 and March 2000,7 certification-training sessions were held and 289 WDCA's were certified, with …

Evaluations Of Nicarbazin-Treated Pellets For Reducing The Laying And Viability Of Canada Goose Eggs, Kurt C. Vercauteren, Michael J. Pipas, Kenneth L. Tope
Wildlife Damage Management Conference Proceedings
The number of Canada geese (Branta canadensis) nesting in the United States is increasing rapidly, generating more complaints and problems associated with them. Overabundant geese can be a nuisance, threaten human health and safety, and cause damage to property. Nicarbazin (NCZ), a coccidiostat used in chicken production, has been documented to reduce egg production and viability. The reduction of reproduction through the use of NCZ could be a valuable aspect of an overall integrated goose management plan. We conducted studies at 5 sites in Nebraska in spring 2000 to evaluate the efficacy of NCZ-treated pellets for reducing the laying and …

History And Future Of Wildlife Damage Management Conference, Daniel J. Decker
History And Future Of Wildlife Damage Management Conference, Daniel J. Decker
Wildlife Damage Management Conference Proceedings
The Eastern Wildlife Damage Management (EWDM) Conference was developed (1st conference held in 1983) to focus on people-wildlife interaction issues occurring in the eastern U.S. Developed as a Renewable Resources Extension Act activity, the purpose of the conference was to improve wildlife resource management and increase outputs of agricultural and forestry commodities. A primary planning issue for the 1st EWDM Conference was whether to represent the conference focus as wildlife damage "control" or "management." Control was selected initially, but the title evolved since then to be replaced by "management," reflecting the central role of wildlife conflict mitigation in wildlife management. …
Capsaicin-Treated Seed As A Squirrel Deterrent At Birdfeeders, Paul D. Curtis, Elizabeth D. Rowland, Gwen B. Curtis, Joseph A. Dunn
Capsaicin-Treated Seed As A Squirrel Deterrent At Birdfeeders, Paul D. Curtis, Elizabeth D. Rowland, Gwen B. Curtis, Joseph A. Dunn
Wildlife Damage Management Conference Proceedings
Eastern gray squirrels (Sciurus carolinensis) are considered to be a pest by many bird-lovers because they take significant quantities of seed from birdfeeders. None of the available methods of protecting birdseed against squirrels is completely effective. We assessed the efficacy of treating birdseed with capsaicin oleoresin as a means of deterring squirrels. Consumption of treated and untreated whole, black-oil sunflower seed was compared by carrying out one-choice feeding trials at 3 sites near Ithaca, New York, from 11 May to 24 June 1999. The heat strength of the treated seed was 40,000 Scoville Heat Units (SHUs) (2,424 ppm) on the …
Survey Of Factors Affecting The Success Of Clemson Beaver Pond Levelers Installed In Mississippi By Wildlife Services, Dale L. Nolte, Seth R. Swafford, Charles A. Sloan
Survey Of Factors Affecting The Success Of Clemson Beaver Pond Levelers Installed In Mississippi By Wildlife Services, Dale L. Nolte, Seth R. Swafford, Charles A. Sloan
Wildlife Damage Management Conference Proceedings
Clemson beaver pond levelers were developed as a tool to enable land managers to manipulate water flow past beaver (Castor canadensis) dams. Wildlife Services has installed several of these devices in collaboration with landowners. We conducted a survey to determine if we could identify factors that impacted whether the devices were meeting landowner objectives. Fifty percent of the 40 levelers surveyed were still operating and regarded as successful. Factors considered in the survey included management objectives, time since the leveler was installed, watershed characteristics, physical attributes of the stream and of the beaver dam where the leveler was installed, and …

Gis Use In Oral Rabies Vaccine Programs, Patricia R. Bright, Elizabeth Schmidt, Francois Elvinger, Michelle M. Weisbarth, R. F. Bulley, Cynthia L. Mills
Wildlife Damage Management Conference Proceedings
Frequent human and domestic animal exposures to rabid wildlife have raised the public's awareness, leading to an increase in the number of wildlife submissions for rabies testing as well as an increase in the number of people requiring post exposure prophylaxis treatment. During 1998 and 1999, the Health and Human Services Department of a densely populated urban/suburban county in Virginia received a total of 955 animal submissions for rabies testing. Wildlife accounted for 714 of the submissions. Seventy-nine of the submitted wildlife were found dead, 445 were killed or euthanized for testing (190 unknown). Of the wildlife submissions, 152 (21%) …

Wildlife Damage Management Conference Proceedings
One can be a student of Tom Peters, management visionary and futurist, or Gary San Julian, a leader in the academics of wildlife damage management (WDM), but that is not necessary to be impressed and excited by the rapid trends and unpredictable events that are altering how we think about and attempt to manage the nation's precious wildlife resources. Because of the boundless propensity of mankind to develop, inhabit, and alter the landscape, wildlife managers of today and the future require different strategies, tools, and skills than those who did such a fine job of conservation and management in past …
Bird Damage To Tropical Fruit In South Florida, Eric A. Tillman, Annamaria Van Doom, Michael L. Avery
Bird Damage To Tropical Fruit In South Florida, Eric A. Tillman, Annamaria Van Doom, Michael L. Avery
Wildlife Damage Management Conference Proceedings
In Dade County, Florida, the production of tropical fruit is a major component of the agricultural industry with total sales amounting to $73.5 million in the 1997-1998 season. Two types of fruit in particular, lychee (Litchi chinensis) and longan (Euphoria longana), are rapidly emerging in economic importance with a combined annual value of over $19 million. For many lychee and longan growers, bird damage is perceived to be a significant constraint to production, yet there is no published information on the extent of damage caused by birds. In 1999, we initiated research to identify the bird species responsible for longan …

Comparison Of Standard And Modified Soft Catch® Traps For Capturing Coyotes, Bobcats, And Raccoons, Jan F. Kamler, Chad Richardson, Philip S. Gipson
Wildlife Damage Management Conference Proceedings
Capture rates and injury rates of coyotes (Canis latrans), bobcats {Lynx rufus), and raccoons (Procyon lotor) captured in standard No. 3 Soft Catch® traps were compared to those captured in the same trap type modified with the Taos Lightening Spring™ (TLS) double torsion spring. All traps were equipped with Paws-I-Trip™ pan tension devices and were successful in excluding most small nontarget species. We captured 15 coyotes and 17 bobcats from October 1995 to March 1997. In addition, 23 raccoons, a large nontarget species, were captured. Capture rates for coyotes were higher (P < 0.10) in TLS modified traps (92%) than standard traps (27%), whereas capture rates were similar (P > 0.10) for raccoons (85% and 67%, respectively) and …
Evaluating Norway Rat Response To Attractant And Repellant Odors To Improve Rodenticide Baiting Effectiveness, Stephen A. Shumake, A. A. Hakim
Evaluating Norway Rat Response To Attractant And Repellant Odors To Improve Rodenticide Baiting Effectiveness, Stephen A. Shumake, A. A. Hakim
Wildlife Damage Management Conference Proceedings
Control of rodent infestations using acute-rodenticide baiting is frequently fraught with difficulties involving bait-shyness and neophobic effects. To simulate some of the parameters encountered in baiting situations, pre-weighed quantities of Environmental Protection Agency (EPA) standard challenge bait mixture were used as a highly palatable bait base to induce feeding without the need for food deprivation in Wistar-strain laboratory albino rats. Individual animals were tested for attractant effects of 3 odors (rat urine, preputial gland extract, and carbon disulfide) and a natural repellent odor (coyote urine) in an observation area constructed of clear plastic panels containing a central alley and 2 …

Spatial Movements In Response To Baiting Female White-Tailed Deer, Scott C. Williams, Anthony J. Denicola
Wildlife Damage Management Conference Proceedings
A better understanding of the manipulation of white-tailed deer movement patterns in response to bait has implications for future management of increasing suburban herds. We gathered radio telemetry data for 10 female and 1 male deer over a 1-year period with artificial feeding stations activated in spring and fall. Data were triangulated in the computer program Topo!, transferred into home range program CALHOME, and imported into Arc View for analysis. Mean annual home range size was 57.7 ha with mean core area of 8.4 ha. Spatial changes in behavior of all deer were witnessed in response to bait including core …
Wildlife Damage In The Suburbs: Conflicts In A Human-Wildlife Landscape, Rebecca Field
Wildlife Damage In The Suburbs: Conflicts In A Human-Wildlife Landscape, Rebecca Field
Wildlife Damage Management Conference Proceedings
The sprawling communities surrounding cities pose a paradox for wildlife. Suburban habitat, with parks, greenways, and planned open spaces, provide attractive habitat with abundant resources for some wildlife species. Yet the landscape is dominated by human activities and disturbances. Species with little tolerance for human disturbance and habitat changes have difficulty maintaining their populations in suburban environments. Yet more adaptable species flourish in suburban areas where there are less predators, increased food resources, and abundant habitat for cover and raising young. The resulting overabundant wildlife populations pose increasing problems for biologists, wildlife damage practitioners, and the public. Management of urban …
